What spark plugs are used in the Buick Excelle three-cylinder engine?

[LeZachary]

Buick Excelle three-cylinder engines use NGK spark plugs. Here is an introduction to spark plugs: 1. Function: Their role is to discharge the pulsed high voltage sent by the high-voltage wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the cylinder. 2. Main types: Standard spark plugs, insulator-protruding spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, surface-jump spark plugs, etc. 3. Function: The spark plug's role is to introduce tens of thousands of volts of high voltage into the combustion chamber and generate an electric spark to ignite the air-fuel mixture. Working in conjunction with the ignition system and fuel supply system, it enables the engine to perform work, collectively determining the engine's performance to a large extent.
